We have had many many rescue dogs. All except for our Dena..who we currently love..were from the streets. My husband worked in areas of Los Angeles where for some reason, a hole people would dump their dogs. He, over the years, has brought home some of the best dogs in the world. We have and still do, feel WE were so fortunate to have had them in our lives. We never knew anything about their previous lives, but they all came with fears and scars. It was like peeling an onion. Layers had to come off before these sweet critters could heal. Just accept that your dozer had this crappy existence and take little steps with him. Before you know it..he will be whole again and love you more than you can imagine. I am so missing these special babies of mine as I write this. Remember..soon you will have replaced his fears with love..and thank you for opening your heart.
